LT8500EUHH#PBF

The LT8500EUHH#PBF is a 48-channel LED PWM Generator with 12-bit resolution and 50MHz cascadable serial interface. Each channel has an individually adjustable 12-bit (4096-step) PWM register. All controls are programmable via a simple serial data interface. Three banks of 16-channels each can be configured such that they operate 120° out-of-phase with each other. The LT8500 features two diagnostic information flags of synchronization error and open LED. The flags are sent, with additional state information, on the serial data interface during status read back. The 50MHz cascadable serial data interface includes buffering and skew-balancing, making the chip suitable for PWM intensive applications such as large screen LCD dynamic backlighting and mono-, multi- and full-colour LED displays.
